Blackberry plant named ‘Hall&#39;s Beauty’

ABSTRACT

A new and distinct blackberry cultivar that originated from seed produced from a cross between the female blackberry plant ‘NZ 9629R-1’ (unpatented) and the male parent blackberry plant ‘ORUS 1939-4’ (unpatented). This new blackberry cultivar can be distinguished by its very large, many petaled, and attractive flowers, medium to high yields of large and very sweet flavored berries with good firmness and color and that are early ripening, and the trailing plant is completely thornless.

Latin name of the genus and species of the plant claimed: ‘HALL'S BEAUTY’ is a blackberry plant that is Rubus subg. Rubus Watson.

Variety denomination: The new blackberry plant claimed is of the variety denominated ‘Hall's Beauty’ Rubus subg. Rubus Watson.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct blackberry cultivar designated ‘Hall's Beauty’ and botanically known as Rubus subg. Rubus Watson. This new blackberry cultivar was discovered in Corvallis, Oreg. in July 2008 and originated from a cross between the female blackberry plant ‘NZ 9629R-1’ (unpatented) and the male parent blackberry plant ‘ORDS 1939-4’ (unpatented). ‘Hall's Beauty’s spinelessness is derived from ‘Lincoln Logan’ (unpatented) that can be found as a parent four and five generations back in ‘Hall's Beauty’s pedigree. The original seedling of the new cultivar was asexually propagated at a nursery in Benton County, Oreg. The new cultivar was established in vitro from a cane cutting and microcuttings have been taken and rooted from this sort of culture. The present invention has been found to be stable and reproduce true to type through successive asexual propagations.

SUMMARY OF THE INVENTION

The following are the most outstanding and distinguishing characteristics of this new cultivar when grown under normal horticultural practices in Oregon. 1. A high plant vigor as compared to ‘Black Diamond’ (unpatented); 2. Trailing growth habit; 3. Early date for 50% of ripe fruit compared to ‘Black Diamond’ (unpatented) and ‘Marion’ (unpatented); 4. Weight of fruit is heavier compared to ‘Marion’ (unpatented) and similar to ‘Columbia Star’ (U.S. Plant Pat. No. 25,532); 5. Fruit are sweeter (higher soluble solids) than ‘Black Diamond’ (unpatented), ‘Columbia Star’ (U.S. Plant Pat. No. 25,532), and ‘Marion’ (unpatented); 6. Flowers are much larger in diameter, with many more petals per flower, than those of the commercial cultivars ‘Black Diamond’ (unpatented), ‘Columbia Star’ (U.S. Plant Pat. No. 25,532), and ‘Marion’ (unpatented).

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

This new blackberry plant is illustrated by the accompanying photographs that show the flowers, fruit and entire plants; the colors shown are as true as can be reasonably obtained by conventional photographic procedures.

COMPARISON WITH PARENTAL AND COMMERCIAL CULTIVARS

‘Hall's Beauty’ differs from the female parent ‘NZ 9629R-1’ (unpatented) in that ‘Hall's Beauty’ has large-sized, glossy, fruit (6.3 g), while ‘NZ 9629R-1’ has slightly pubescent fruit that are smaller (4.5 g).

‘Hall's Beauty’ differs from the male parent blackberry plant ‘ORDS 1939-4’ (unpatented) in that it is spineless, has conic, glossy and sweet berries and moderate to high yields, while ‘ORDS 1939-4’ (unpatented) is spiny and has barrel shaped pubescent berries, and moderate yields.

‘Hall's Beauty’ flowers are much larger in diameter, with many more petals per flower, than those of the commercial cultivars ‘Black Diamond’ (unpatented), ‘Columbia Star’ (U.S. Plant Pat. No. 25,532) and ‘Marion’ (unpatented). ‘Hall's Beauty’ differs from ‘Marion’ (unpatented) in that ‘Hall's Beauty’ is spineless, early ripening and has medium-large (6.3 g), firm fruit while ‘Marion’ (unpatented) is spiny and ripens the crop in midseason and has medium yields of medium sized (5.0 g) and soft fruit that are unevenly shaped. ‘Hall's Beauty’ differs from the commercial cultivar ‘Black Diamond’ (unpatented) in that ‘Hall's Beauty’ carries the ‘Lincoln Logan’ (unpatented) source of spinelessness and therefore the canes are completely spineless and the plants are vigorous with medium-large (6.3 g) fruit that are an excellent, sweet, aromatic flavor, while ‘Black Diamond’ (unpatented) carries the ‘Austin Thornless’ (unpatented) source of spinelessness and so has spines on the base of the canes and the plants are not vigorous and they produce smaller (5.2 g) fruit with a mild flavor. ‘Hall's Beauty’ further differs from the commercial cultivars ‘Black Diamond’ (unpatented), ‘Marion’ (unpatented) and ‘Columbia Star’ (U.S. Plant Pat. No. 25,532) based on having sweeter (high soluble solids) fruit.

‘Hall's Beauty’ is primarily suited to the machine-harvested, processed-fruit market but is also firm enough for fresh market sales and the large, attractive flowers make it a potential ornamental for homeowners. 

I claim:
 1. A new and distinct cultivar of blackberry plant, substantially as illustrated and described, characterized by its very large, many petaled, and attractive flowers, medium to high yields of large and very sweet flavored berries with good firmness and color and that are early ripening, and the trailing plant is completely thornless.
